FLUME-GATE.

QIEEGIFICATION forming part of Letters Patent No. 704,971Jdated July 15, 1902.

Application filed November 19 i 1901. Serial No; 2, N Infidel-l To all whom it may concern:

Be it known that I, EPHRAIM CAMPBELL, a citizen of the United States, residingat Redlands, in the county of San Bernardino'and -State of California, have inventednew and useful Improvements in Flume- Gates, of which the following is a specification.

An object of this invention is to provide a simple flu me-gate which will maintain a perfeet closure of the outlet when desired and.

which will not'be liablelto clog with sand or other foreign matter when the gate is open.

Another object of this invention is to provide an irrigating fiume-gate in which the ways forthe gate are so constructed and ar-: ranged that the operation of the gate will notv -front elevation of the appliance'with the gate in place to allow a small irrigating-stream to issue. Fig. IV is a. plan section ot the flume-gate on line IV IV, Fig. III. Fig. Vis a front elevation of the appliance with the. gate removed.

This newly-invented fiume-gate comprises a flattened tube 1, oval in cross-section, 'a gate-holder 2, fastened to the tube, near the end thereof, and a gate 3, held by said holder and sliding across the end of the tube and furnished at its lower end with a rounded notch 4, thus to allow the opening in the flame-gate when the gate is nearly closed to be approximately circular, so that when the passage through the gate is brought approximately to the minimum size required for discharging an irrigatingstream its smallest diameter will ,not be less than the smallest diameter of the inlet into the tube. The greatest diameter of the tube is preferably parallel with the inbent edges of theholder.

The gate-holder 2 isvpreferably formed of a plate of metal or other'suitahle material per- *forated with a perforation 5 and bent inward at its edges 6 and 7 to form guides and re silient gate retainers, which extend in a'plane 'nearand preferably, parallel with the plane of the end 8 of the tube. The gate 3 is preferably formed of a metal plate fitting against the end of the tube on the one side and against the inbent edges'on the other side and sliding across the end of the tube 1 and fitting'tightly'between such end and the inbent edgesof the holder;

The plate which forms the holder2 is suffi'ciently resilient to cause the inbent edges to pressupon the gate, so that the same will be tightly held thereby against the'end of the tube, thus to prevent any leakage.

In practical use the tube 1 of the fiumegate may extend through the wall 9 of the fiume, and the length of the tube may practically correspondto the thickness of. the wall. That end of the tube to'which thegate-is apatthepleasure of the constructor. The user may adjust the gate to the appro priate height to allow the necessary quantity of water to flow through the tube.

Thetube, the holder, and the gate are preferably made of galvanized sheet ironfor steel, andthe tube will be cemented orotherwise secured in the wall through which it passes, the holder and the gate being at either the outside or inside of the Hume, at the discretion of the constructor.

By the arrangement shown any sand or other foreign matter which may come in contact with the gate, even to the extent of forming a bank against and around the gate, will have no eiitect upon the friction between the gate-holder and slide, so that the gate will always be held water-tight against the end of the tube whenever the gate is closed, and there will be practically no leakage when the gate is in closed position.

The inturned edges are respectively nearly in the extended piane of the sides of the tube,-so that there is no leverage upon the gate between the tube and said'edges to how the gate, wherefore the gate will fit tightly against the end of the tube to close the same,

and the bonds or bows 10 of the plate may plied maybe either outside or inside the flume,

exert considerable resilient force to hold the gate in place without any liability of bowing the gate in transverse section.

What I claim, and desire to secure by Letters Patent of the United States, is

1. A fiume-gate comprising a tube oval in cross-section; a gate-holder fastened to the tube near the end thereof; and a gate held by said holder and sliding across the end of the tube and furnished in its lower end with a notch.

2. A plate having inbent edges and a perforation between said edges; a tube inserted through the perforation and fastened to the plate and terminating in a plane near the plane in which the inbent edges lie and being beyond the plate; and a sliding gate fitting between saidtube end and said inbent edges.

3. A fiume-gate comprising a perforated plate having inbent edges; a flattened tube fastened to the plate and extending through the perforation and terminating in a plane near the plane in which the inbent edges lie;

gate fitting between said inbent edges and p the end of the tube, the lower end of said'gate being notched to correspond with the openi ng through the tube.

4. A flume-gate comprising a tube to extend through a flume-wall, and a gate-holder fastened to the tube at a distance from the end thereof and extending beyond the end of said tube and terminating in two edges which lie in a plane that extends near the plane of the end of the tube; and a gate fitting against the end of the tube on the one side and against said edges on the other side.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Redlands, California, this 5th day of November, 1901.

EPHRAIM CAMPBELL.
